Read one of my fantasy calculations

The state of a calculation started with Prefer: respond-async (the NBA squad builder and the NBA transfer plan), or of one whose synchronous call answered 503 with a Location to this endpoint. status is queued (with queue_position, the jobs ahead of it), running, done or failed. When done, result is exactly the body the synchronous endpoint returns. When failed, error carries the status and the sentence the synchronous call would have answered. Poll every two or three seconds, a build takes up to about 30. A job is readable for six hours and only by the account that started it: anybody else gets 404. Reading it changes nothing and costs no quota.
